This document lists the Compute Engine rate quotas, which define the number of requests you can make to Compute Engine API methods.
Rate quotas
Rate quotas (also known as API rate limits or API quotas) define the number of requests that can be made to the Compute Engine API. These quotas apply on a per-project basis. Each quota applies to a group of one or more Compute Engine API methods. When you use the gcloud CLI or the Google Cloud console, you are also making requests to the API and these requests count towards your rate quota. If you use service accounts to access the API, that also counts towards your rate quota.
Google enforces rate quotas at a per-minute (60 seconds) interval for each
group. That means if your project reaches the maximum number of API requests
anytime within 60 seconds, you must wait for that rate quota to refill before
making more requests in that group. If your project exceeds a rate quota, you
receive a 403 error with the reason rateLimitExceeded. To resolve this error,
wait a minute then try your request again—the quota should be refilled at
the start of the next interval.
The number of requests that you can make to the Compute Engine API is defined by quota groups as described in the following tables. Each group is counted separately, so you can achieve the maximum quota in each group simultaneously.
Rate quotas for global metrics
The following quota groups apply for all resources unless specified otherwise:
| Quota group Description |
Metric name | Default quota |
|---|---|---|
| Queries Quota for global mutation methods that are not included under other quota metrics. The following
|

Quota per project (defaultPerMinutePerProject):
1500 requests/minute |
| Read requests Quota for global *.get methods. |

the quotas against
the |
compute.googleapis.com/filtered_list_cost_overhead |
Rate per project (ListRequestsFilterCostOverheadPerMinutePerProject):
750k resources filtered out of the list requests per region per minute. As the
quota is charged for every 10k resources, you see the limit as 75 (750k/10k) when you
query for this quota limit on the Google Cloud console.

images.insert, images.setLabels, snapshots.delete,
snapshots.insert, snapshots.setLabels,
machineImages.insert, and machineImages.delete methods. |
compute.googleapis.com/global_resource_write_requests |
Rate per project (GlobalResourceWriteRequestsPerMinutePerProject):
375 requests/minute |
| Heavy-weight mutation requests Quota for patch, delete,
and insert methods for the interconnects resources. |
compute.googleapis.com/heavy_weight_write_requests |
Rate per project (HeavyWeightWriteRequestsPerMinutePerProject):
750 requests/minute |
| Heavy-weight read requests Quota for *.aggregatedList methods. |
compute.googleapis.com/heavy_weight_read_requests |
Rate per project (HeavyWeightReadRequestsPerMinutePerProject):
750 requests/minute |
The following quota groups apply to global APIs with per method quotas:
| Quota group Description |
Metric name | Default limit |
|---|---|---|
| License insert requests Quotas for licenses.insert method. |
compute.googleapis.com/license_insert_requests |
|
| Project set common instance metadata requests Quota for projects.setCommonInstanceMetadata method. |

Rate quotas for regional metrics
The following quotas apply to methods that use regional metrics:
| Quota group Description |
Metric name | Default quota Quota per project per region |
|---|---|---|
| Queries quota for regional and zonal methods that create, modify, or delete Compute Engine resources. For example, instances.insert, disks.update, and
instances.delete methods.
The following
|
compute.googleapis.com/default_per_region |
Queries per minute per region: 1500 |

the quotas against
the |

Request an increase in rate quotas
If you need a higher quota for making API requests, you can request an increase in the API quota from the Google Cloud console. For instructions, see Requesting a higher quota.
